While consciousness is an area widely studied in science and philosophy, many aspects of it remain elusive, and the terminology surrounding consciousness is often used inconsistently. Philosophers differentiate between what they call the easy problems and the hard problem. The easy problems deal with states of being—like the difference between wakefulness and sleep—where scientific explanations may eventually be attainable. These problems focus on behavioral outputs and physiological responses that are relatively straightforward to observe and measure.
